HOT-VATEIL HEATER.

Application filed July 20, 1923.

To all whom it may concern:

Be it known that I, Lnsrnn CHURCHMAN, a citizen of the United States, residing at Bryan, in the county of lVilliams and State of Ohio, have invented certain new and useful Improvements in Hotater Heaters. of which the following is a specification.

This invention relates to hot water heaters and it consists in the novel features herein after described and claimed.

An object of the invention is to provide a water heating attachment adapted to be applied to a furnace and which may be economically and efiiciently used for heating the water by the absorption of the heat units from the products of combustion given off by the fire which heats the furnace.

With this object in view the heater comprises a body adapted to be inserted in the combustion chamber of the furnace at the door opening thereof and which extends into the combustion chamber with its inner portion disposed downwardly therein in order that maximum heating surface may be ex posed to the burning products of combustion. The attachment consists of a hollow body having its interior area divided by a septum wall and with openings provided at one end wall only of the body and located one at each side of the septum wall. Nipples may be connected with the body at the openings and used for connection with water flow pipes. The heater body is oblong in plan and is ogee shaped in side elevation. The opposite end walls of the body are disposed in planes lying at an acute angle to each other.

In the accompanying drawings- Figure 1 is a fragmentary perspective view of a furnace showing the water heater applied.

Figure 2 is a side elevation of the water heater.

Figure 3 is a top plan View of the same.

Figure i is an elevation looking at one end.

Figure 5 is an elevation looking at the opposite end.

Figure 6 is a transverse sectional view out on the line 66 of Figure 2.

Figure 7 is a transverse sectional view cut on the line 77 of Figure 2.

As illustrated in the accompanying drawings the water heater comprises a body 1 which is elongated in plan, oblate in side elevation and rectangular in transverse sec- Serial No. 852,835.

tion. The said body is also ogce shaped in side elevation and that i. to say that its opposite end portions are off-set with relation to each other. The body is hollow. The end alls of the body are disposed in planes lying at an acute angle to each other.

The interior of the body 1 is divided by a. septum wall 2 which joins with the end wall 3 and which at its inner end terminates short of the end wall t of the body. The end wall 3 is provided with openings 5 which are located one at each side of the wall 2 and with which nipples 6 may be connected for joining the body with. water flow pipes (not shown).

The end wall 3 is disposed in a plane lying at a right angle to the median longitudinal dimension of the body 1 and the end wall 4 lies in a. plane disposed at an acute angle to said dimension.

When the water heater attachment is applied to the furnace it is inserted into the combustion chamber through the door opening of the furnace and is held at its out end. portion in the compartment which is provided in the throat of the door opening. The inner portion of the body extends down and into the lower portion of the combustion chamber and near one side thereof and the inclined wall 4 bears against the adjacent edge portions of the castings which form the combustion chamber of the furnace. Thus maximum area of the body is exposed to the heat from the fire in the furnace. The water enters the body 1 through one of the nipples 6 and passes down and! along one side of the septum wall 2, around the inner end of the said wall and up and along the opposite side of the wall and out of the body through the other nipple 6. During its passage through the body 1 and around the septum wall, the water is heated in the manner as hereinbefore described.

Having described the invention what is claimed is A water heating furnace appliance comprising an elongated hollow body having its interior area divided by a septum wall which joins with one end wall of the body and terminates short of the opposite end thereof, the end wall of the body with which the septum wall joins being provided: with openings located one at each side of the septum wall, the walls of the body being otherwise imperforated, the body being ogeeshaped in side elevation, the inner end. edge of the septurn wall being parallel with the end wall of the body with which the septum wall joins, and the opposite end wall of the body being inclined upwardly and outwardly from the adjacent end edge of the septum wall and from the bottom wall of the body to the top wall thereof whereby the space between the inner end edge of the septum wall and the inclined end wall of the body is of greater transverse dimension at the top wall of the 10 body than at the bottom wall thereof.

In testimony whereof I aifix my signature.
